SGRAPER ATTACHMENT FOR ICE-CREAM FREEZERS.

Specification of Letters Patent.

Application filed m 11,1906. Serial No. 325,600.

. To all whom it may concern:

Be it known that I, Wmmsm B. MCFADDEN,Of Syracuse, in-the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Scraper Attachments forIce-Cream Freezers, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and ,exact description;

This invention relates to certain improvements .in scraperattachmentsfor ice cream receptacles, and is parti'cularly'useful in places wherethe ice cream is re tailed 'in small quantities for soda water and smalldishes.

It is customary to serve a'predetermined quantity of this cream at agiven price, and under existing methods, this quantity varies materiallyand usually in excess of that which it is designed to supply, by reasonof the fact that the ladle or other dish with which it is removed iromthe main receptacle is always more or'less heaped, which of course,materially reduces the profit from the sales of the cream. I

i The main object, therefore, of my invention is to provide' the mainreceptacle with a removable scraper attachment which is self-retainingand. is of such construction as to permit the lid to be placed inoperative position or removed without interfering with the attachment,and when the lid is ofi affords means against which the open side ofthe, filled ladle or other dish may be drawn, to remove excess cream sothat the same amount may-be supplied to each customer.

Another object is to provide the scraper blade. or bar- A withadjustable clamps which areadapted to swing horizontally and laterallyto conform to different sizes and shapes of receptacles, upon which suchattachment may be placed.

Other objects and uses will appear in the following description.

'In the drawings, Figure 1 is a top plan of a portion of an ice creamreceptacle and my improved scraper attachment mounted thereon. Fig. 2 isa sectional view taken on-line 22 Fig. 1, a lower'portionvofthereceptacle'being broken away. Fig. 3 is a top planof thescraperattachment seen in Figs. 1 and 2, showing the is clamps in onepositipn in full lines and in another position by dotted lines. Figs. 4and 5 are sectional views taken respectively on lines '4.4 Fig. 3, and55 Fig. 4.

In demonstmtingthe practicability of my invention I have shown a scraperattachment consisting essentially of a scraper bar -1- and clamps 2-which are adjustably secured to the opposite ends of the 1m 1- and'areadapted to slip over the upper edge, and to engage the inner and outerfaces of an ice cream recepta'cle as .-c, having a lid -bas best seen inFig.

--2. These receptacles as a vary in diameter, somebeing straight orvertical, while others are flaring either downwardly or upwardly, and inorder that the.

scraper attachment may be adapted to fit on the upper edges of suchreceptacles, the clamps 2- are adjustapertures 7 in the inner arms ofthe clamps 2,

and are provided with enlarged heads'8 located between said arms toprevent endwise displacement of the clamps from the pins or studs Inother words, these pins 3 are pivotally connected to the ends of theplate l to swing horizontally and the clamps -2 are pivoted to the'outerends of the pins to swing laterally or vertically and by this relativeassociation of the parts 1, 2and3, clamps -2 may I be adjusted tofit-upon the upper edge of any form or size of receptacle to hold thebar 1- rigidly within the upper end of said receptacle.

I have shown each clarnp 2- as consisting of a one piece bar of springmetal bent upon itself forming 0pposite arms united at the top andhaving their lower edges, constituting spring jaws, spring tensionedtoward each other but -separable against their own spring tension, toreceive therupper edge of the receptacle a--.

The outer edge of the'clamp 2- which engages the outer face of thereceptacle zis-preferably straight vertically, as best shown 2 and 5,and being ofcomparatively thin spring metal does not in terfere withtheplacing or removal-,of the lid as b to and from its operative positionas clearly shown in Fig. 2. I

The inner arm 'of each clamp --2- is preferably curved with its convexside toward the straight arm 'andmay be formed with serrations 9- toafford greater gripping power.

The upper ends of the arms of each clamp -'2,

just below their junction are spaced apart a sufiicient distance toreceive betweenthem the enlarged head of the pin or stud 3-- so as topermit the clamp to turn freely upon said pin.

The exact form of the scraper bar l and clamps 2- is immaterial, theprinciple feature being to adjustably connect the clamps to the bar sothat they may be adjusted horizontally and vertically to conform todifferent sizes and forms of. receptacles as -a--. Y

The bar 1 is shown in the drawings as consisting of a blade having aknife edge 10- and rounded ends --11 which latter, allows the clamps 2to e be placed close to the ends of-the we and. at the same time to beturned .otal screws The contiguous faces of the bar -1- and eyes 4 whichengage each other, are substantially flat so that when the clamps are.swu l laterally or horizontally upon their pivots to the an es shown byfull and dotor swung laterally upon their pivted lines in Fig.3, theblade will be rigidly held against turning inthe-bear'ings -'7 of theclamps.

In placing this scraper attachment upon areceptacle, it is simplynecessary to slide clamps 2 down over the upper edges of'said receptacleuntil the scraper blade or bar --l assumes aposition within the mainreceptacle in a substantially horizontal position, .as best seen inFigs. 1 andv2, the spring tension of 'theclamps serving to retain them,together withthe blade or bar,

in position, the outer arms of the clamps lying flatwise .against theouter face of the receptacle --a.', taper: mit the lid l to be readilyplaced upon, or removed from said recepacle.

In using this device, supported in the manner described within thereceptacle -a-, the scraper bar -1, which is at one side of the centerof the receptacle is directly in the path of the ladle with which thecream is withdrawn, so that the open side of the ladle may be easily andquickly drawn across the inner edge of the bar --1- to remove any excessof, cream which may;

the scraper-bar to swing horizontally to adapt said attachmen}: fordiilerent sizes of receptacles.

2. An attachment for ice cream receptacles consisting at a scraper bar,horizontally swinging studs pivoted to theends 0! the bar and clampspiyoted to said studs.

3. An attachment-tor ice cream receptacles consisting of .ascraper bar,clamp supports hinged to the ends'ot the bar .to-swing horizontally andclamps hinged to said supports 4 to swing vertically.

a scraper bar, and spring clamps plvgotally connectedto the ends of thescraper bar to swing horizontally.

In witness whereof I'have hereunto set my hand "this 7th day of July1906.
